  • 현재 지능적 서비스의 핵심 기술은 딥러닝 즉 신경망, 그리고 GPU 병렬 컴퓨팅 및 빅 데이터와 같은 병렬 분산 처리 기술이다. 하지만 미래의 전 세계적으로 공유된 온톨로지를 통한 지능적 서비스 및 지식 공유 서비스에서는 지식의 표현 및 추론을 위하여 신경망보다 더 나은 방법이 있다. 그것은 시맨틱 웹의 표준 규칙 언어인 RIF 혹은 SWRL의 IF-THEN의 지식 표현이며, 이러한 규칙을 rete 알고리즘을 이용하여 효율적으로 추론할 수 있다. 하지만 단일 컴퓨터에서 동작하는 rete 알고리즘의 처리 규칙 수가 100,000개가 될 경우 그 성능이 수 십 분으로 매우 안 좋아지며, 분명한 한계가 존재한다. 따라서 본 논문에서는 rete 알고리즘의 병렬 및 분산 처리에 대한 과거로부터 현재까지의 연구 내용을 정리 분석하며, 이를 통해 효율적인 rete 알고리즘의 구현을 위해 어떤 측면들이 고려되어야 하는지를 살펴본다.

  • K-Pop is hugely promoted offline/online in East Asia, while efforts to promote it elsewhere are kept to a minimum. Whilst addressing the role of digital marketing in the promotion of K-Pop in the Brazilian music industry this study aims to demonstrate that K-pop will provide its audience with a unique and engaging experience if it thinks globally and acts locally in its marketing and communication strategies. A survey of K-Pop's world fan base was carried out online with 1,074 fans to determine the validity of the hypothesis. The results have demonstrated the need to adapt global and intercultural strategies to local markets with increasing brand awareness through utilizing digital marketing. For example, to increase K-Pop's popularity and market share in Brazil, it is not required to sing in Brazilian Portuguese, contrary to what might be perceived but fully singing in English would help breaking into the market dominated by domestic music as songs would have a higher probability to be included in the international soundtrack of a Brazilian telenovela and promote the K-Pop artist not only across Brazil but also give the artist exposure in all the markets the Brazilian telenovela is exported to, opening an entry door to those markets. K-Pop audience segmentation and psychographic profiling is crucial to the understanding of each market's consumer's preferences, likes, dislikes and their buying habits as it was proven through Brazil's digital media, social media, digital music market and K-Pop market analysis within the global context of the study. It should be also considered that brand extensions are not standard everywhere and that there are cultures where different product categories are not directly associated with its main corporate owner which requires extensive local market knowledge to succeed. The primary and secondary data research that we conducted for this study intended to demonstrate that K-Pop can be successful in Brazil and in Latin America and increase their local and regional market share if digital marketing and communication strategies are tailored to each individual market.

  • One of the goals of this article is to continue the momentum begun by emerging scholarship on theory and practice of writing about visual culture of and in Southeast Asia. I hope to offer culturally sensitive and embodied ways of looking at images and objects as sites/sights of cultural knowledge as further theoretical intervention. The argument put forward in my essay is three-fold: first, I critique the prevailing logocentric approach in the field of Southeast Asian Studies and I argue that in a postcolonial, global, and transnational period, it is important to be inclusive of other objects as sites/sights of social, political and cultural analysis beyond written and oral texts. Second, I argue that although it has its own political and theoretical problems, the evolving field of Visual Studies as it is practiced in the United States is one of many ways to decolonize the prevailing logocentric approach to Southeast Asian Studies. Third, I argue that if one reads these Euro-American derived theories of vision and visuality through the lens of what Walter Mignolo calls "colonial difference(s)," then Visual Studies as an evolving field has the potential to offer more nuanced local ways of looking at and understanding objects, vision, and visuality. Last, I point out that unlike in the West where there is an understanding of pure, objective and empirical vision, local Southeast Asian perspectives on objects and visions are more embodied and multi-sensorial. I argue that if one is ethically mindful of the local cultural ways of seeing and knowing objects, then the evolving field of Visual Studies offers a much-needed intervention to the privileged, lingering logocentric approach to Southeast Asian Studies. Moreover, these alternative methods might help to decolonize method and theory in academic disciplines that were invented during the colonial period.

  • Although many guidelines for pancreatic cystic neoplasms focus on the management of intraductal papillary mucinous neoplasm of the pancreas (IPMN) at the highest oncological risk, there are many issues that surgeons need to consider at the time to plan the surgical procedures based on characteristics of IPMN subtypes, such as multiplicity of branch duct-IPMN (BD-IPMN) and intraductal spreading of main duct-IPMN (MD-IPMN). For multifocal BD-IPMN, partial pancreatectomy would be selected to remove BD-IPMN with predictors of malignancy, while the other lesions without risk factors can be left, although total pancreatectomy might be considered if the patients have a strong family history of pancreatic cancer. Partial pancreatectomy would be also adequate procedure for MD-IPMN if negative surgical margin for high-grade dysplasia or invasive carcinoma were achieved. It has become to be well-known that patients with BD-IPMN are at increased risk for developing not only IPMN-associated pancreatic ductal adenocarcinoma (PDAC) but also PDAC independent from the IPMN. Hence, the detection of a concomitant PDAC is also an important focus for strategies after resection of BD-IPMNs. Our recent analysis of patients after partial pancreatectomy for MD-IPMN with negative surgical margin identified an unexpected recurrence pattern, which we called "monoclonal skip" recurrence. MD-IPMN seems to be disseminated in the pancreatic ductal systems and MD-IPMN with identical genetic background was detected in the remnant pancreas even in a long time after index surgery. We proposed strategies of postoperative surveillance based on characteristics and natural history of each morphological subtype.

  • Recently, there are many researches have been studying for analyzing user interests and emotions based on users profiles and diverse information from Social Network Services (SNSs) due to their popularities. However, most of traditional researches are focusing on their researches based on single resource such as text, image, hash tag, and more, in order to obtain what user emotions are. Hence, this paper propose a method for obtaining user emotional information by analyzing texts and images both from Instagram which is one of the well-known image based SNSs. In order to extract emotional information from given images, we firstly apply GRAB-CUT algorithm to retrieve objects from given images. These retrieved objects will be regenerated by their representative colors, and compared with emotional vocabulary table for extracting which vocabularies are the most appropriate for the given images. Afterward, we will extract emotional vocabularies from text information in the comments for the given images, based on frequencies of adjective words. Finally, we will measure WUP similarities between adjective words and emotional words which extracted from the previous step. We believe that it is possible to obtain more precise user emotional information if we analyzed images and texts both time.

  • This paper presents a case study involving one Korean primary school student and people around him in order to explore the reading process in English of a young Korean EFL learner and to investigate the social context in which his reading takes place. Six participants were included in the study (one primary school student and five adult participants). The student participant was asked to read a text in English and translate what he read into Korean and the teacher participants were asked to listen to the student's reading. Semi-structured interview was used to collect data from the student as well as five adult participants (his private tutor, his parent, his state school teacher, and two other state school teachers). The analysis reveals four characteristics of the way a young EFL learner approaches reading: word-by-word reading, disconnected word recognition, selective use of cues, and lack of awareness of difficulties. The four characteristics of Kilsu's reading suggest that reading can become a wild guessing game for young foreign learners, if they give selective attention to unimportant cues while reading. The pedagogical implications of this study are also discussed to help teachers designing reading lessons for young learners.

  • The management science was concerned about how to use the main point of the management science model and it's technique by the rational primary factors. The problem's definition, estabilished of the model and it's solving. These function are very difficult and important problems, what is more important, are the model of management science's real prosecution to the manager and management scientist. The management science give us a clue to the solution of a business problem. To get needs conclusion and achieving the estabilished object, we must implement a plan, a stratgem, a policy. If we were not implementing the recommended items, we may call the estabilished model and problem solving impractical, ivory-tower theorizing. But, the implementation of management science model is a complicated problem that is involved mutual relations of managers and management scientist, linkage parts member and the resources of organization. And the other problems of implementation are very complicated problems composed of technologic and economic, social and politic, psychological. This paper reports the implementation of a success that possibly studies a fluent and a chief cause to systematic analysis. Then, first of all I will define of implementation and from these, construction of a unity system, I continue with a catch hold of a main point and a fluent for the successful implementation.

  • Representation has been main topic in teaching and learning mathematics for a long time. Moreover, teachers' deficiency of representation about fraction results in teaching algorithms without conceptual understanding. So, this paper was conducted to investigate and analysize the elementary preservice mathematics teachers' representation about fraction. 38 elementary preservice mathematics teachers participated in this study. This study results showed that, the only model of a fraction that was familiar to the preservice teachers was the part of whole one. And research showed that, they solved the problems about fraction well using algorithms but seldom express the sentence which illustrates the meaning of the operation by a fraction. Specially, the division aspect of a fraction was not familiar nor readily accepted. It menas that preservice teachers are used to using algorithms without a conceptual understanding of the meaning of the operation by a fraction. This results give us some implications. Most of all, teaching programs in preservice mathematics teachers education have to devise to form a network among the concepts in relation to fraction. And we must emphasize how to teach and what to teach in preservice mathematics teachers education course. Finally, we have to invent the various materials which can be used to educate both preservice teachers and elementary school students. If we want to improve the mathematical ability of students, we will concentrate preservice teachers education.
